CURRENT-OPERATED PUMP.

SPECIFICATION forming part of Letters Patent No. 787,153, dated April 11, 1905.

Application filed July '7, 1903. Renewed March 13, 1905. Serial No. 249.9i1.

Be it known that \ve inrrm zsos DAVIS Dawso and FRANK HauIL'roX, citizens of the United States, residing at Beardstown, in the county of Cass and State of Illinois, have invented certain new and useful Improvements in Current-i)perated Pumps, of which the tollowing is a specilication.

This invention has relation to current-operated submerged pumps; and it consists in the novel construction and arrangement of its parts, as hereinafter described.

The object of the invention is to provide a (1lI'I'LIIb-()pQliIlICLl submerged pump adapted to draw water from or 'force water into an adjacent reservoir or receptacle.

In the accompanying drawings, Figure I is a side elevation of the invention. Fig. 2 a longitudinal sectional view of the same. Fig. I} is an end view of the pump, and Fig. I is a horizontal sectional view of the pump.

The frame I is located in a body of running water, the casing 2 being adapted to move vertically in said frame 1. One end of the chain 3 is attached to said casing, the said chain then passing up over pulleys I and 5 and having attached atits other end the counterbalance-weight 6. The pump 7 is located within the casing 2 and is connected with the pipe b. said pump being preferably composed of two cylinders 9 9, each having a checkvalve It) and a valved piston 11. The waterwheel I) is journaled to the arms 13, which in turn are attached to the casingZ, said wheel being provided on its periphery with a number of paddles II, said paddles being adapted to enter chute 15, which is also attached to the casiugQ. The levers 16 are 'fulcrumed to the casing 2 and are pivoted at their lower ends to the piston-rods 17. To the upper end of each lever I1) is pivoted a pitman 18, the other end of which is pivoted to a crank on IE), attached to the wheel 12.

In operation the device works as follows:

The casing) and the inclosed pump 7 are placed in a stream of running water. The water passing through the casingQ and out through the chute comes in contact with the paddles II and revolves the wheel I2, which, through the pitman l8, levers 16, and the piston-rods IT, rcciprocates the pistons 11. Previous to which, however, one end of the pipe 8 is placed in a reservoir, and as the said pistons II reciprocate they pump the water from the said reservoir. through the pipe 8, into the running stream. It, however, it is desired to pump water into the said reservoir, the valves in the pistons 11 and the check-valves IO are reversed and the water is pumped from the running stream,through the pipe 8, into the reservoir.

Having described our invention, what we claim as new, and desire to secure by Letters Patent, is

I. A pump adapted to move vertically, a casing surroundingsaid pump and adapted to move with the same. a water-wheel suitably mounted and adapted to move vertically and simultaneously with said pump and casing, said pump being operatively connected with said wheel, said wheel being adapted to be operated by the water passing through said casing and a counterbalance for the vertically moving parts.

A pump adapted to move vertically. a casingsurroundingsaid pump and adapted to move with the same, a water-wheel suitably mounted and adapted to move vertically and simultaneously with said pump and easing, a chute connected at one end with said casing and receiving the paddles of said wheel at its opposite end, said pump being operatively connected to said wheel, said wheel being adapted to be operated by the water passing through said casing a counterbalance for the vertically-moving parts.

In testimony whereof we aliix our signatures in presence of two witnesses.
